Description

Transmission power adjustment method, electronic device, and storage medium

Technical Field

The present application relates to the field of intelligent terminal technologies, and in particular, to a transmission power adjustment method, an electronic device, and a storage medium.

Background

When the connection between the earphone and the electronic device has a large interference (for example, when the earphone is far away from the electronic device), the earphone requests the electronic device to increase the transmission power, so that the communication quality between the earphone and the electronic device is ensured. However, in order to ensure the efficiency of sound reception and improve the hearing experience of the user, some earphones do not consider the actual communication situation, and always request the electronic device to increase the transmission power, and the transmission power increase request is not stopped until the electronic device increases the transmission power to the maximum transmission power. The electronic device may also increase the transmit power to the maximum transmit power directly upon request by the headset. However, part of the application scenarios of the headset do not require as high a transmission power, and therefore waste of power consumption is easily caused.

It should be understood that in this application, "/" means "or" means "unless otherwise indicated. For example, A/B may represent A or B. In the present application, "and/or" is only one kind of association relation describing an associated object, and means that three kinds of relations may exist. For example, a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. "at least one" means one or more. "plurality" means two or more than two.

It should be understood that the order of the steps shown in the flowcharts herein may be changed, and some may be omitted.

As shown in fig. 1, when the connection between the earphone and the electronic device has a large interference (for example, when the earphone is far away from the electronic device), the earphone may request the electronic device to increase the transmission power, but some earphones may request the electronic device to increase the transmission power after connecting the electronic device without considering the actual situation until the electronic device increases the transmission power to the maximum transmission power of the electronic device, for example, the maximum transmission power is the power corresponding to Powerlever 10. During the period, the earphone will always send the request for increasing the transmission power to the electronic device, and will not stop sending the request for increasing the transmission power until the transmission power of the electronic device is increased to the power corresponding to Powerlever 10. The electronic device will increase the transmission power to the maximum, such as to the power corresponding to Powerlever 10, upon request from the headset. However, sometimes the application scenario of the headset does not require so high transmission power, and the above procedure and result inevitably results in waste of power consumption.

In order to solve the problem that the electronic device always increases the transmission power according to the request of the earphone for increasing the transmission power in the process, thereby causing the waste of power consumption, the embodiment of the application provides a transmission power adjustment method, so as to avoid the problem that the power consumption is abnormally increased due to the fact that the transmission power is continuously increased when the earphone is in a music scene. Specifically, according to the embodiment of the application, when the earphone requests to increase the transmission power, whether the transmission power is increased or not is determined by judging the application scene, and power consumption waste caused by the fact that the electronic device increases the transmission power according to an unreasonable transmission power increase request provided by the earphone can be avoided.

It is understood that the electronic device in the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, and electronic devices such as a cellular phone, a Personal Digital Assistant (PDA), an Artificial Intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, and/or a smart city device. The embodiment of the present application does not specifically limit the specific form of the apparatus. The earphone in this application also can be other bluetooth playback devices, such as bluetooth speaker etc..

The transmit power adjustment method provided by the present application is described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic diagram of signaling interaction between the headset and the electronic device. As shown in fig. 2, the headset may request the electronic device to increase transmit POWER by sending LMP-INCR-POWER-REQ signaling to the electronic device. The electronic device may increase the transmit POWER based on LMP-INCR-POWER-REQ signaling sent by the headset. Specifically, the electronic device increases the transmission POWER according to the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling, and it can be understood that different LMP-INCR-POWER-REQ signaling may correspond to the same or different transmission POWER increase values, and the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling may be set according to an actual situation, which is not limited herein.

If the electronic equipment receives the LMP-INCR-POWER-REQ signaling sent by the earphone and determines that the current transmission POWER is the highest transmission POWER (for example, the highest transmission POWER is the POWER corresponding to the Powerlever 10), the electronic equipment sends the LMP-MAX-POWER signaling to the earphone, informs that the current transmission POWER of the electronic equipment of the earphone is the highest transmission POWER, and cannot continuously increase the POWER request. The headset will stop sending POWER up requests to the electronic device when receiving the LMP-MAX-POWER signaling.

And the electronic equipment increases the transmission POWER according to the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling. It can be understood that the transmission POWER increase value corresponding to the LMP-INCR-POWER-REQ signaling may be set according to actual situations, and two different LMP-INCR-POWER-REQ signaling may correspond to different transmission POWER increase values, which is not limited herein.

In the signaling interaction process shown in fig. 2, the headset always sends LMP-INCR-POWER-REQ signaling to the electronic device, so that the transmission POWER of the electronic device is increased to the maximum transmission POWER. In order to solve the above problem, an embodiment of the present application provides a transmit power adjustment method shown in fig. 3. The method is applied to the electronic equipment. The electronic device may include bluetooth firmware (BTC), and the method may be applied to the BTC of the electronic device. The electronic device establishes a bluetooth connection with the headset, as shown in fig. 3, the method may include:

301, receiving LMP-INCR-POWER-REQ signaling sent by the earphone.

The LMP-INCR-POWER-REQ signaling is used to request the electronic device to increase transmit POWER. It is understood that the LMP-INCR-POWER-REQ signaling is only illustrated here, and the headset may also request the electronic device to increase the transmission POWER by sending other commands.

302, it is determined whether the quality of communication with the headset meets a preset communication threshold.

After the electronic equipment receives the LMP-INCR-POWER-REQ signaling sent by the earphone, the electronic equipment determines the communication quality with the earphone and determines whether the communication quality with the earphone meets a preset communication threshold value.

In some embodiments of the present application, the communication quality includes a retransmission rate, and the retransmission rate is used to determine an efficiency of data transmission from the electronic device to the headset, and may be a probability of retransmission of the signal from the electronic device to the headset. The determining whether the communication quality with the headset meets a preset communication threshold comprises: determining whether a retransmission rate with a headset is less than or equal to the retransmission rate threshold; if the retransmission rate between the earphone and the mobile terminal is less than or equal to the retransmission rate threshold value, the communication quality between the earphone and the mobile terminal is determined to meet a preset communication threshold value; and if the retransmission rate between the earphone and the user equipment is determined to be larger than the retransmission rate threshold value, determining that the communication quality between the user equipment and the earphone does not meet the preset communication threshold value.

The retransmission rate threshold may be set according to practical situations, for example, set to 50%. And if the electronic equipment determines that the retransmission rate between the electronic equipment and the earphone is less than or equal to 50%, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets a preset communication threshold value. And if the electronic equipment determines that the retransmission rate between the electronic equipment and the earphone is more than 50%, the electronic equipment determines that the communication quality between the electronic equipment and the earphone does not meet the preset communication threshold.

In some embodiments of the present application, the communication quality includes a Received Signal Strength Indicator (RSSI) of a Received Signal of the headset, and the determining whether the communication quality with the headset satisfies a preset communication threshold includes: determining whether the RSSI with the headset is less than or equal to a strength threshold; if the electronic device determines that the RSSI of the earphone is less than or equal to the strength threshold, the electronic device determines that the communication quality between the electronic device and the earphone does not meet the preset communication threshold. And if the electronic equipment determines that the RSSI of the earphone is greater than the strength threshold value, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets a preset communication threshold value.

In some embodiments of the present application, the communication quality includes a bit error rate of the headset, and the bit error rate may be a bit error probability of the headset transmitting a signal to the electronic device. The determining whether the communication quality with the headset meets a preset communication threshold comprises: determining whether the error rate of the earphone is less than or equal to an error rate threshold value; and if the electronic equipment determines that the error rate of the earphone is less than or equal to the error rate threshold value, the electronic equipment determines that the communication quality between the electronic equipment and the earphone meets a preset communication threshold value. And if the electronic equipment determines that the error rate of the earphone is greater than the error rate threshold value, the electronic equipment determines that the communication quality between the electronic equipment and the earphone does not meet a preset communication threshold value.

If the communication quality with the headset is determined to meet the preset communication threshold, 303 is executed without increasing the transmission power. If it is determined that the communication quality with the headset meets the preset communication threshold, 304 is performed to increase the transmission power.

As shown in fig. 3, the current transmission Power of the electronic device is illustrated by taking the Power corresponding to Power Level 7 as an example, and if it is determined that the communication quality with the headset meets the preset communication threshold, the transmission Power is not increased, that is, the Power corresponding to the current transmission Power Level 7 is maintained; and if the communication quality with the earphone is determined not to meet the preset communication threshold, increasing the current transmitting Power from the Power corresponding to the Power Level 7 to the Power corresponding to the Power Level 8. In some embodiments of the present application, 302 in fig. 3, after determining whether the quality of communication with the headset meets a preset communication threshold, the method further comprises: counting the times of not increasing the transmitting POWER after receiving LMP-INCR-POWER-REQ signaling sent by the earphone; and if the times meet a preset quantity condition, sending an LMP-MAX-POWER signaling to the earphone.

The LMP-MAX-POWER signaling is used to indicate that the current transmission POWER of the electronic device is the highest transmission POWER, and the transmission POWER cannot be increased continuously, and the headset may be notified: the electronic device is already at the highest transmit power and cannot increase the transmit power any more. By sending LMP-MAX-POWER signaling to the headset, the headset may be prevented from continuing to send transmit POWER up requests to the electronic device. It can be understood that, the LMP-MAX-POWER signaling here is only an example, and the electronic device may further notify the headset that the current transmission POWER of the electronic device is the highest transmission POWER and cannot be continuously increased by sending another instruction to the headset, so as to avoid the headset from continuously sending a transmission POWER increase request to the electronic device.

The method can count the times that the transmission POWER is not increased after the electronic equipment receives the LMP-INCR-POWER-REQ signaling sent by the earphone after the electronic equipment is connected with the earphone. Or, the number of times that the transmission POWER is not increased after the LMP-INCR-POWER-REQ signaling sent by the earphone is received in the preset time period may be counted. The preset time period can be set according to actual conditions. For example, the preset time period may include a time period from the last time the electronic device increased the transmission power to the current time. When the excessive transmission power is not increased after the electronic device establishes the bluetooth connection with the headset, the preset time period may also include a time period from the time when the electronic device establishes the bluetooth connection with the headset to the current time.

The preset number condition may include a preset number threshold, and the determining whether the number of times satisfies the preset number condition includes: whether the number of times of judgment is greater than or equal to a preset number threshold value or not may be set according to an actual situation, and is not limited herein, for example, the preset number threshold value may be set to 1, 2, or 3.

In some embodiments of the present application, when the preset number threshold is set to 1, the method includes: and if the communication quality with the earphone meets a preset communication threshold value after receiving the LMP-INCR-POWER-REQ signaling sent by the earphone, sending the LMP-MAX-POWER signaling to the earphone. That is, when the communication quality with the earphone is determined to meet the preset communication threshold after the LMP-INCR-POWER-REQ signaling sent by the earphone is received for the first time, the LMP-MAX-POWER signaling is directly sent to the earphone so as to prevent the earphone from continuously sending a transmission POWER improvement request to the electronic equipment. When the fact that the earphone requests the electronic equipment to improve the transmission POWER under the condition that the communication quality is normal is found for the first time, the LMP-MAX-POWER signaling is directly sent to the earphone, and the phenomenon that the follow-up earphone continuously requests the electronic equipment to improve the transmission POWER under the condition that the communication quality is normal can be avoided.

When the value of the preset number threshold is set to be larger, if the number of times that the transmission POWER is not increased after receiving the LMP-INCR-POWER-REQ signaling sent by the earphone meets the preset number condition, the following conditions can be determined: the earphone requests the electronic device to increase the transmission power more times when the communication quality meets the preset communication threshold. When the communication quality of the earphone meets the preset communication threshold value, the LMP-MAX-POWER signaling is sent to the earphone under the condition that the number of times of requests for increasing the transmission POWER to the electronic equipment is large, so that the condition that the earphone always requests for increasing the transmission POWER to the electronic equipment when the communication quality meets the preset communication threshold value can be avoided. Meanwhile, when the condition that the number of times of requests for requesting the electronic equipment to increase the transmission POWER is large when the communication quality meets the preset communication threshold is determined, the LMP-MAX-POWER signaling is sent to the earphone to prevent the earphone from continuously sending the request for increasing the transmission POWER, so that the condition that the earphone cannot normally request the electronic equipment to increase the transmission POWER due to the fact that the earphone directly refuses to request the electronic equipment to increase the transmission POWER after requesting the electronic equipment to increase the transmission POWER when the communication quality meets the preset communication threshold by accident can be avoided.

According to the embodiment, when the earphone requests to improve the transmission power, whether the transmission power is improved or not is determined according to the communication quality with the earphone, and the transmission power of the electronic equipment is improved when the retransmission rate with the earphone is determined to meet the preset improvement condition, so that power consumption waste caused by improvement of the transmission power of the electronic equipment according to an unreasonable transmission power improvement request provided by the earphone can be avoided.

The frequency of not increasing the transmission POWER after receiving the LMP-INCR-POWER-REQ signaling sent by the earphone meets the preset quantity condition, and when the LMP-MAX-POWER signaling is sent to the earphone, the transmission POWER of the electronic equipment may not reach the highest transmission POWER of the electronic equipment actually. In the following, some specific embodiments after the electronic device sends the LMP-MAX-POWER signaling to the headset will be described with reference to the embodiments.

In some embodiments of the present application, after sending LMP-MAX-POWER signaling to the headset, the method further comprises: and determining whether the communication quality with the earphone meets a preset communication threshold value according to a preset time interval. And if the communication quality with the earphone is determined not to meet the preset communication threshold, actively improving the transmitting power. If the communication quality with the earphone is determined to meet the preset communication threshold, no processing is performed, and the process is ended. It will be appreciated that the above method may be performed when the electronic device is not currently transmitting at the highest transmit power but the headset is informed that the current transmit power is the highest transmit power. If the current transmission power of the electronic device is the highest transmission power, the method is not executed.

By the method, the situation that the transmission efficiency between the electronic equipment and the earphone is low due to the fact that the electronic equipment cannot actively improve the transmitting power when the current transmitting power of the electronic equipment cannot meet normal communication with the earphone after the electronic equipment executes the method when the current transmitting power of the electronic equipment is not the highest transmitting power but informs the earphone that the current transmitting power is the highest transmitting power can be avoided, and therefore the accuracy of transmitting power adjustment is improved.

When signaling interaction is performed between the earphone and the electronic device shown in fig. 2, after the electronic device receives a transmission power increase request sent by the earphone each time, the transmission power may be directly increased according to the request, and unless the current transmission power is the highest transmission power, the transmission power request of the earphone may not be replied. In some embodiments, however, the electronic device replies to the request for the increase in the transmit power of the headset each time it receives the request for the increase in the transmit power sent by the headset, as shown in fig. 4. Fig. 4 is a schematic diagram of signaling interaction between the headset and the electronic device. As shown in fig. 4, the headset may request the electronic device to increase the transmit POWER by sending LL-POWER-CONTROL-REQ signaling to the electronic device. The electronic equipment increases the transmission POWER based on the LL-POWER-CONTROL-REQ signaling sent by the earphone, and sends an LL-POWER-CONTROL-RSP instruction to the earphone after the transmission POWER is increased.

As shown in table 1, the LL-POWER-CONTROL-REQ signaling may include three CONTROL parameters (CONTROL Data, CtrData): physical channel (PHY), difference (Delta), transmit power (TxPower). The PHY is used to indicate a signal used for signaling. Delta is used to indicate the transmission power value for which a change is requested, a positive number indicates the transmission power value for which an increase is requested, and a negative number indicates the transmission power value for which a decrease is requested. For example, Delta 1 indicates a request to increase the transmit power by 1db, and Delta-1 indicates a request to decrease the transmit power by 1 db. TxPower represents the current transmit power of the local terminal. If a headset sends LL-POWER-CONTROL-REQ signaling, TxPower in the command indicates the current transmission POWER of the headset.

TABLE 1

As shown in Table 2, six CONTROL parameters (CONTROL Data, CtrData) may be included in the LL-POWER-CONTROL-RSP signaling: a minimum value (Min); maximum value (Max); reserved bit (RFU); difference (Delta), transmit Power (TxPower), Acceptable maximum Power Reduction (APR). Where Min is used to indicate whether the current transmission power is the minimum transmission power, Min 0 indicates that the current transmission power is not the minimum transmission power, and Min 1 indicates that the current transmission power is the minimum transmission power. Max is used to indicate whether the current transmission power is the maximum transmission power, Max 0 indicates that the current transmission power is not the maximum transmission power, and Max 1 indicates that the current transmission power is the maximum transmission power. Delta is used for representing the transmission power value changed this time, positive numbers represent the transmission power value increased this time, and negative numbers represent the transmission power value decreased this time. For example, Delta 1 represents the current increase of the transmission power by 1db, and Delta-1 represents the current decrease of the transmission power by 1 db. TxPower represents the current transmit power of the local terminal. If an electronic device issues LL-POWER-CONTROL-RSP signaling, TxPower in the instruction indicates the current transmission POWER of the electronic device.

TABLE 2

For convenience of description, in the signaling interaction shown in fig. 4, the key control parameter added in each signaling is used to indicate the specific content corresponding to each signaling. For example, LL-POWER-CONTROL-REQ (Delta 1) is used to indicate that the headset requests an increase in transmit POWER of 1db from the electronic device. LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 8) indicates that the electronic equipment has been increased by 1db of transmission POWER (Delta 1) according to LL-POWER-CONTROL-REQ (Delta 1) signaling, the transmission POWER of the current electronic equipment is POWER lever8 corresponding POWER (Txpower 8), and the transmission POWER of the current electronic equipment is not maximum transmission POWER (Max 0).

If the electronic equipment increases the transmission POWER, when the current transmission POWER is determined to be the highest transmission POWER (for example, the highest transmission POWER is the POWER corresponding to the Powerlever 10), the electronic equipment sends LL-POWER-CONTROL-RSP (Max 1, Delta 1, Txpower 10) signaling to the earphone, the earphone is informed that the transmission POWER (Delta 1) of 1db is increased according to the LL-POWER-CONTROL-REQ signaling, the current transmission POWER of the electronic equipment is the POWER corresponding to the Powerlever 10, the current transmission POWER (Max 1) is the highest transmission POWER, and the POWER request cannot be increased continuously. When the headset receives the LL-POWER-CONTROL-RSP signaling with Max of 1, the headset stops sending the POWER-up request to the electronic equipment.

In the signaling interaction process shown in fig. 4, the headset always sends LL-POWER-CONTROL-REQ signaling to the electronic device, so as to increase the transmission POWER of the electronic device to the maximum transmission POWER. In order to solve the above problem, an embodiment of the present application provides a transmit power adjustment method shown in fig. 5. The method is applied to the electronic equipment. The electronic device may include bluetooth firmware (BTC), and the method may be applied to the BTC of the electronic device. The electronic device establishes a bluetooth connection with the headset, as shown in fig. 5, the method may include:

and 501, receiving LL-POWER-CONTROL-REQ signaling.

For example, LL-POWER-CONTROL-REQ (Delta 1) signaling is used to request the electronic device to increase the transmit POWER by 1 db.

502, it is determined whether the quality of the communication with the headset meets a preset communication threshold.

After receiving the LL-POWER-CONTROL-REQ signaling sent by the earphone, the electronic equipment determines the communication quality with the earphone and determines whether the communication quality with the earphone meets a preset communication threshold value.

If the communication quality with the earphone is determined to meet the preset communication threshold, 503 is executed, and the transmitting power is not increased; if it is determined that the communication quality with the headset meets the preset communication threshold, 504 is performed to increase the transmit power.

After the electronic device increases the transmission POWER based on the LL-POWER-CONTROL-REQ signaling, the electronic device may send LL-POWER-CONTROL-RSP signaling, such as LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 8), to the headset. As shown in fig. 5, the current transmission Power of the electronic device is illustrated by taking the Power corresponding to Power Level 7 as an example, and if it is determined that the communication quality with the headset meets the preset communication threshold, the transmission Power is not increased, that is, the Power corresponding to the current transmission Power Level 7 is maintained; and if the communication quality with the earphone is determined not to meet the preset communication threshold, increasing the current transmitting Power from the Power corresponding to the Power Level 7 to the Power corresponding to the Power Level 8.

According to the embodiment, when the earphone requests to improve the transmission power, whether the transmission power is improved or not is determined according to the communication quality with the earphone, and when the retransmission rate with the earphone is determined to meet the preset improvement condition, the transmission power of the electronic equipment is improved, so that power consumption waste caused by improvement of the transmission power of the electronic equipment according to an unreasonable transmission power improvement request provided by the earphone can be avoided.

In some embodiments of the present application, as shown in fig. 6, at 502 in fig. 5, after determining whether the communication quality with the headset satisfies the preset communication threshold, if the electronic device determines that the communication quality with the headset satisfies the preset communication threshold, 601 is executed to send a rejection signaling to the headset. The rejection signaling indicates that the transmission power is rejected from being increased according to the transmission power increase request, and may be used to inform the bluetooth playing device that the transmission power is not increased. As shown in fig. 7, the transmission POWER before the electronic device receives the LL-POWER-CONTROL-REQ signaling is the POWER corresponding to Powerlever 7, and after the electronic device determines that the communication quality with the headset meets the preset communication threshold, the electronic device sends LL-POWER-CONTROL-RSP (Max 0, Delta 0, Txpower 7) to the headset, where Delta 0 indicates that the transmission POWER is not increased according to the LL-POWER-CONTROL-REQ signaling. It will be appreciated that the next time the electronic device receives the LL-POWER-CONTROL-REQ signaling again and determines that the quality of communication with the headset still satisfies the preset communication threshold, the electronic device continues to send rejection signaling, i.e., LL-POWER-CONTROL-RSP (Max 0, Delta 0, Txpower 7), to the headset.

In some embodiments of the present application, after determining whether the communication quality with the headset satisfies the preset communication threshold, the electronic device may count the number of times that the transmission POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset, according to 502 in fig. 5; and if the times meet a preset quantity condition, sending an improvement signaling to the earphone.

For some specific embodiments of counting the number of times that the transmission POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the earphone, reference may be made to the related description of the number of times that the transmission POWER is not increased after receiving the LMP-INCR-POWER-REQ signaling sent by the earphone in fig. 3, and the preset number condition may also be referred to the description related to the embodiment in fig. 3, which is not described herein again.

In some embodiments of the present application, the number of times that the rejection signaling is sent to the headset by the electronic device may be determined as the number of times that the transmission POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset.

The boost signaling is used to tell the headset that the transmit power has been increased. It is understood that the format of the enhanced signaling sent when the transmission power is not increased may be the same as or different from the format of the enhanced signaling sent when the transmission power is increased. When the earphone receives the increasing signaling sent when the transmitting power is increased and the increasing signaling sent when the transmitting power is not increased, the earphone can determine that the transmitting power of the electronic equipment is increased. For example, when the electronic device has a transmission POWER corresponding to Powerlever 7, and when the electronic device receives LL-POWER-CONTROL-REQ (Delta 1) signaling, it determines that the number of times that the communication quality with the headset meets a preset communication threshold in a period from the last time of increasing the transmission POWER to the current time satisfies a preset number condition, e.g., it determines that the number of consecutive transmissions of the rejection signaling is greater than or equal to the preset rejection threshold, and does not increase the transmission POWER, it directly transmits LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 8) to the headset, informs that the headset has increased the transmission POWER of 1db according to the LL-POWER-CONTROL-REQ (Delta 1) signaling, and the transmission POWER of the current electronic device is a POWER corresponding to Powerlever 8, and the transmission POWER of the current electronic device is not the maximum transmission POWER, and the electronic device actually does not increase the transmission POWER, the current transmission power of the electronic device is still the power lever 7.

It can be understood that, after the electronic device does not increase the transmission POWER and sends the increase signaling to the headset, if the LL-POWER-CONTROL-REQ signaling is received again and it is determined that the communication quality with the headset satisfies the preset communication threshold, the transmission POWER is still not increased, and the increase signaling is continuously sent to the headset once. It will be appreciated that the increase signaling sent by the electronic device at different times may be different without the electronic device increasing the transmit power. For example, in the case that the electronic device does not increase the transmission POWER, the increase signaling sent by the electronic device a to the headset a for the first time may be LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 8), and the increase signaling sent by the electronic device a to the headset a for the second time may be LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 9), where the sending time of the first time is earlier than the sending time of the second time. That is, the multiple increase signaling sent by the electronic device to the same headset may vary without the electronic device increasing the transmit power. For example, the Txpower value in the up signaling with the later transmission time may be greater than the Txpower value in the up signaling with the earlier transmission time. Under the condition that the electronic equipment does not improve the transmitting power, different improvement signaling is sent to the earphone, so that the condition that the same improvement signaling is sent to the earphone all the time to cause the error report of the earphone can be avoided.

Further, in some embodiments of the present application, if the number of times of sending the boost signaling to the headset without boosting the power is greater than the preset number of times, the highest power signaling is sent to the headset. By sending the highest power signaling to the headset, the headset is prevented from requesting an increase in transmit power from the electronic device at all times.

The highest power signaling is used to tell the headset: the current transmission power of the electronic device is the highest transmission power, and the transmission power cannot be increased continuously. By sending the highest POWER signaling (e.g., sending LL-POWER-CONTROL-REQ signaling) to the headset when the actual transmit POWER of the electronic device is not the highest transmit POWER, the headset may be prevented from continuing to send transmit POWER-up requests to the electronic device. For example, the highest POWER signaling may be LL-POWER-CONTROL-RSP (Max 1, Delta a, Txpower B), Max 1 indicates that the current transmission POWER of the electronic device is the highest transmission POWER, a is a number greater than 0, a is a transmission POWER value informing that the headset is increased (the transmission POWER may not be increased by the actual electronic device), and the specific value of a may be set according to actual situations. The headset can determine the transmission power of the electronic device according to the Txpower B in the instruction, so that the value of B is larger than the transmission power of the electronic device known by the headset last time. For example, if the last signaling sent by the electronic device to the headset is LL-POWER-CONTROL-RSP (Max 0, Delta 1, Txpower 7), the highest POWER signaling sent by the electronic device to the headset at this time may be LL-POWER-CONTROL-RSP (Max 1, Delta a, Txpower B), where the value of B should be greater than 7, and the value of B may be equal to the value of a plus 7.

It is understood that in some embodiments of the present application, the electronic device may count the number of times the transmission POWER is not increased after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset; and if the times meet a preset quantity condition, directly sending a highest power instruction to the earphone. In other embodiments of the present application, the highest POWER command may be sent directly to the headset when the electronic device determines that the quality of communication with the headset satisfies the preset communication threshold after receiving the LL-POWER-CONTROL-REQ signaling sent by the headset.

In some embodiments of the present application, after determining whether the communication quality with the headset meets the preset communication threshold, the electronic device may count the number of times of sending the rejection signaling, executing 502 in fig. 5; and if the sending times meet a preset quantity condition, sending a signaling for improving or a signaling for the highest power to the earphone. It can be understood that, in this embodiment, after the sending times satisfy the condition of the preset number, the number of times of sending the enhanced signaling is counted; and if the times of sending the signaling improvement to the earphone are more than the preset times, sending the highest power signaling to the earphone.

In some embodiments of the present application, after sending the highest power signaling to the headset, it may be determined whether the communication quality with the headset meets a preset communication threshold according to a preset time interval. And if the communication quality with the earphone is determined not to meet the preset communication threshold, actively improving the transmitting power. If the communication quality with the earphone is determined to meet the preset communication threshold, no processing is performed, and the process is ended. The preset time interval may be set according to actual conditions, and is not limited herein. By the method, the situation that the transmission efficiency between the electronic equipment and the earphone is low due to the fact that the electronic equipment cannot actively improve the transmitting power when the current transmitting power of the electronic equipment cannot meet normal communication with the earphone after the electronic equipment executes the method when the current transmitting power of the electronic equipment is not the highest transmitting power but informs the earphone that the current transmitting power is the highest transmitting power can be avoided, and the accuracy of transmitting power adjustment is improved.

It is understood that the electronic device may or may not notify the headset after actively increasing the transmission power. For example, the electronic device may notify the headset that the transmit POWER has been increased, such as POWER up signaling, via LL-POWER-CONTROL-IND signaling. As shown in Table 3, six CONTROL parameters (CONTROL Data, CtrData) may be included in the LL-POWER-CONTROL-IND signaling: a minimum value (Min); maximum value (Max); reserved bit (RFU); difference (Delta), transmit power (TxPower), physical channel (PHY). The specific meaning of each control parameter in table 3 can be referred to the introduction of the relevant control parameters in tables 1 and 2, and will not be described herein again.

TABLE 3

For example, after the electronic device actively increases the transmission POWER (POWER lever7 before increasing and POWER lever8 after actively increasing), the electronic device sends LL-POWER-CONTROL-IND (Max 0, Delta 1, Txpower 8) signaling to the headset to inform the headset that the transmission POWER is increased by 1db, the current transmission POWER of the electronic device is the POWER corresponding to POWER lever8, and the current transmission POWER of the electronic device is not the maximum transmission POWER. It will be appreciated that the headset receives

LL-POWER-CONTROL-IND signaling, when determining that the electronic device is not currently at the highest transmission POWER, may continue to request the electronic device to increase the transmission POWER, at this time, the current status may be processed according to the method shown in fig. 5 and the method in the embodiment related to fig. 5, for example, when rejecting an unreasonable transmission POWER increase request of the headset or making an unreasonable transmission POWER request of the headset, an increase signaling or a highest POWER signaling is sent to the headset.
